You Are Here: Scientists Unveil Precise Map Of More Than A Billion Stars

The European Space Agency has released a chart of the exact positions of many stars in the Milky Way and neighboring galaxies. But the map only shows a small fraction of what’s out there.

Wednesday was the day astronomers said goodbye to the old Milky Way they had known and loved and hello to a new view of our home galaxy.

A European Space Agency mission called Gaia just released a long-awaited treasure trove of data: precise measurements of 1.7 billion stars.

It’s unprecedented for scientists to know the exact brightness, distances, motions and colors of more than a billion stars. The information will yield the best three-dimensional map of our galaxy ever.

“This is a very big deal. I’ve been working on trying to understand the Milky Way and the formation of the Milky Way for a large fraction of my scientific career, and the amount of information this is revealing in some sense is thousands or even hundreds of thousands of times larger than any amount of information we’ve had previously,” said David Hogg, an astrophysicist at New York University and the Flatiron Institute. “We’re really talking about an immense change to our knowledge about the Milky Way.”

The Gaia spacecraft launched in 2013 and is orbiting our sun, about a million miles away from Earth. Although it has surveyed a huge number of stars, Gaia is charting only about 1 percent of what is out there. The Milky Way contains around 100 billion stars

For 7 million stars, Gaia even has measurements showing their velocity as they move toward or away from the spacecraft. “This is just a fantastic new addition,” said Anthony Brown of the Netherlands’ Leiden University, with the Gaia Data Processing and Analysis Consortium.

In 2016, Gaia released some initial results but that was just a tease compared with Wednesday’s massive data dump. Astronomers around the world have been planning how to attack it for months, knowing that discoveries are just waiting in there for the taking.

“Enjoy it,” Antonella Vallenari, another member of the consortium from the Astronomical Observatory of Padua in Italy, said at a news conference as she announced that the data was becoming available.

The European team presented new images of our galaxy based on some initial analyses of the data, along with little movies that simulated what it would be like to fly through the stars. “It’s not fake, it’s real measurements,” Brown said. “We know exactly where the stars are.”

Scientists around the world who were watching the event online struggled to take it all in. “This is like massive scientific progress and we were blinked an image,” said Jackie Faherty, an astronomer at the American Museum of Natural History, one of more than a dozen astronomers who woke up before dawn and gathered together at the Flatiron Institute in New York City to watch.

Then it was time to play, as the scientists bent their heads over their laptops and tried to download data. Researchers are expecting a slew of discoveries in the coming hours and days, but analyses will go on for years and even decades.

“This is the data we’re going to be working on for the rest of my career. Probably no data set will rival this,” Faherty said. “It’s the excitement of the day that we see it. It’s why we were up at 5 a.m. to get here. It’s exciting to be around each other and trying to get the data all at once. It’s a day we’re going to remember.”

NY Man Planned to Blow Himself Up at Washington Mall

Published

on

Police and FBI agents searched a Hudson Valley home Wednesday after learning about a man who was allegedly building a bomb in order to blow himself up in Washington D.C., two law enforcement officials told News 4 New York.

Investigators said they were concerned the man, identified as Paul Rosenfeld, at the home on Slocum Avenue in Orangetown was in the process of acquiring bomb parts.

Officials tell News 4 Rosenfeld had no criminal history but had told a reporter in Pennsylvania he planned to blow himself up on the Washington Mall around Election Day because he was angry about the country’s direction. 

He had no plans to hurt anyone else, officials said. He is believed to be a lone actor not affiliated with any international terror group or ideology.

Trump ‘demanding’ answers from Saudis about missing writer

Published

on

WASHINGTON (AP) — President Donald Trump said Wednesday the U.S. is “demanding” answers from Saudi Arabia about the disappearance of a well-known Saudi writer and government critic Turkish authorities say was slain inside his country’s diplomatic mission in Istanbul.

Trump said he plans to invite to the White House the fiancée of Jamal Khashoggi, a writer for The Washington Post who has not been seen since he entered the Saudi consulate on Oct. 2 to get paperwork for his marriage.

Members of Congress have grown increasingly insistent that the administration find out what happened to Khashoggi. The Saudi government has become a closer ally under Trump and some lawmakers warn that relations could be jeopardized if it turns out the kingdom was involved in his disappearance.

Trump told reporters in the Oval Office that he has a call in to the fiancée, Hatice Cengiz, who had been waiting outside the consulate when Khashoggi went inside and has appealed to the president and first lady Melania Trump for help.

Trump said nobody knows exactly what happened and expressed hope that Khashoggi is not dead. He also said he had spoken with the Saudis about what he called a “bad situation,” but he did not disclose details of his conversations.

Saudi Arabia denies involvement in the disappearance of Khashoggi, a former insider in Saudi government circles who has been living in self-imposed exile in the U.S. for the past year after fleeing a crackdown on intellectuals and activists in the country.

White House press secretary Sarah Huckabee Sanders said White House national security adviser John Bolton and White House senior adviser Jared Kushner spoke on Tuesday to Saudi Arabian Crown Prince Mohammed bin Salman about Khashoggi. Secretary of State Mike Pompeo then had a follow-up call with the crown prince to reiterate the U.S. request for information.

While angry members of Congress likely won’t cause the administration to turn away from Prince Mohammed and end decades of close security ties with Saudi Arabia, they could throw a wrench into arms sales that require their approval and demand the U.S. scale back support for the Saudi military campaign against Iran-backed rebels in Yemen.

Republican Sen. Bob Corker, chairman of the Senate Foreign Relations Committee, said “there will definitely be consequences” if it turns out the Saudis were involved in Khashoggi disappearance. Republican Sen. Lindsey Graham of South Carolina said it would be “devastating” to the U.S.-Saudi relationship.

Sen. Chris Murphy, D-Conn, said if Saudi Arabia had lured a U.S. resident into a consulate and killed him, “it’s time for the United States to rethink our military, political and economic relationship with Saudi Arabia.” But he said it was unclear whether the Trump administration was willing to “go beyond words.”

Sen. Rand Paul, R-Ky., a longtime critic of the Saudi government, said he’ll try to force a vote in the Senate this week blocking U.S. arms sales to Saudi Arabia. He told local radio in his home state Tuesday that he wants to end the arms shipments if there’s “any indication” the Saudis are “implicated in killing this journalist that was critical of them.”

Trump’s comments Wednesday were the toughest yet from his administration on the Khashoggi case. Officials have expressed concern but refused even to entertain questions about what the consequences would be if Turkish allegations turn out to be true. Pompeo has called on the Saudi government to conduct a thorough investigation and to be transparent about its results.

The reaction from European governments has also been cautious. British Foreign Secretary Jeremy Hunt told his Saudi counterpart that if media reports about Khashoggi were correct, it “would be extremely concerning and the U.K. will treat the incident very seriously,” according to the Foreign Office.

The Saudi ambassador to Washington, Prince Khalid bin Salman bin Abdulaziz, has described the allegations as “malicious leaks and grim rumors” and said the kingdom is “gravely concerned” about Khashoggi. Saudi officials maintain he left the consulate shortly after entering, although it has failed to provide evidence.

Washington Post CEO and publisher Fred Ryan said reports suggested the journalist was victim of “state-sponsored, cold-blooded murder.” He demanded answers in a statement Tuesday, saying “Silence, denials and delays are not acceptable.”

Analysts said there were reasons for skepticism about the Turkish account. Ties between Ankara and Riyadh are at a low point over Turkey’s support for Qatar in that country’s yearlong dispute with Saudi Arabia and other Gulf nations. Saudi Arabia, a Sunni Muslim power, is also annoyed by Ankara’s rapprochement with the kingdom’s Shiite archrival, Iran.

Saudi authorities’ failure to provide video footage of Khashoggi’s movements at the consulate to rebut the Turkish allegations have only deepened suspicions.

The Trump administration, from the president on down, is heavily invested in the Saudi relationship. That’s unlikely to change, said Robin Wright, a scholar at the Wilson Center think tank and close friend of the missing writer. The administration’s Middle East agenda heavily depends on the Saudis, including efforts to counter Iranian influence in the region, fight extremism and build support for an expected plan for peace between Israel and the Palestinians.

Indication of those stakes came within four months of Trump taking office, when Saudi Arabia became his first destination on a presidential trip and he announced $110 billion in proposed arms sales.

Prince Mohammed has introduced some economic and social reforms, allowing women to drive and opening movie theaters in the deeply conservative Muslim nation. The flip side, however, is that he’s also squelched dissent and imprisoned activists. He has championed the three-year military campaign against Iranian-backed Houthi rebels in Yemen that has pushed that nation toward famine and caused many civilian deaths.

Still, the Trump administration last month stood behind its support for that campaign with weapons, logistics and intelligence, certifying that the Saudis were taken adequate steps to prevent civilian despite mounting evidence to the contrary.

Karen Elliott House, a veteran writer on Saudi affairs and chair of the board of trustees at RAND Corp., said U.S. support for the Yemen war is likely to be the focus of congressional criticism but won’t endanger a relationship that has endured for decades, underpinned by shared strategic interests. Even under the Obama administration, which had difficult relations with Riyadh compared with Trump, there were some $65 billion in completed arms sales.

“The U.S.-Saudi relationship is certainly not about shared moral values,” House said. “It’s about shared security interests.”
